Good luck, you will need it
It is the greatest thing you will ever experience, but also one of the hardest. From the first night home, you wonder why the hospital would allow someone so inexperienced to take home a precious little baby. She won't come with directions either.
Every night you will freak out at every little noise or movement, worrying about if she is okay or not. It is tough mentally/emotionally/even physically, but man they are awesome. My little boy is 8 wks and 1 day and time has just FLEW by... I can see waking up one day and him being all grown up. Enjoy it. Don't get too caught up with all of the stress. Make a point to go out without the baby once a month or so in order to remain sane.
